8. On this happy occasion, I wish to invite my brother bishops from all over the world to join the Successor of Peter, during this time of spiritual grace that the Lord offers us, in recalling the precious gift of faith. We want to celebrate this Year in a worthy and fruitful manner. Reflection on the faith will have to be intensified, so as to help all believers in Christ to acquire a more conscious and vigorous adherence to the Gospel, especially at a time of profound change such as humanity is currently experiencing. We will have the opportunity to profess our faith in the Risen Lord in our cathedrals and in the churches of the whole world; in our homes and among our families, so that everyone may feel a strong need to know better and to transmit to future generations the faith of all times. Religious communities as well as parish communities, and all ecclesial bodies old and new, are to find a way, during this Year, to make a public profession of the Credo.
